Volcanic Eruptions & Mountain-Building Forces Illustrate the creation & changing of landforms that have occurred through geologic processes.

Volcanoes can form at any point where the crust is weak. They mostly form along boundaries of Earth’s plates because that is where the rocks tend to be.

Presentation transcript:

Aim: Describe Hot Spots and the Ring of Fire. Do Now: Describe how divergent, convergent, and transform plate boundaries move.

Why are scientists worried about the hot spot under Yellowstone national park?

How do volcanic Islands form?

How do we define a Hot Spot? Hot spot – spot where magma rises to the surface of a plate and volcanoes forms. More volcanoes form as the plate moves over this spot. Mantle Plume– an area of hot rock (magma) that rises from the mantle-core boundary In which compass direction is the Pacific Plate moving? Motion of Pacific Plate Click Here Northwest

Determine how the following features are related

How do you describe the Ring of Fire? The Ring of Fire is a zone of frequent earthquakes and volcanic eruptions that encircles the edges of the Pacific Ocean at plate boundaries.

Summary Questions How are the locations of earthquakes, mountains and volcanoes related? What regions of North & South America show the greatest amount of crustal activity? According to your map and the ESRT, what are the chances of having a volcanic eruption or earthquake occur at your home? Why is the perimeter around the Pacific Ocean referred to as the “Ring of Fire”?
